Decoding Seven Basic Odors by Investigating Pharmacophores and Molecular Features of Odorants (2024)

FAQs

What are the 7 basic odors? ›

Methods: We adopted an in-silico approach to study key and common odorants features with seven fundamental odors (floral, fruity, minty, nutty, pungent, sweet, and woody).

These classes are as fol lows: (1) camphoraceous, (2) pungent, (3) ethereal, (4) floral, (5) pepperminty, (6) musky, and (7) putrid.

Now, researchers have used mathematics to describe odors systematically and simplify them into 10 categories: fragrant, woody/resinous, fruity (non-citrus), chemical, minty/peppermint, sweet, popcorn, lemon, pungent and decayed.

Gas leaks, garlic breath, skunks in the neighborhood—ah, the scent of thiols. The human nose is particularly sensitive to these sulfur-containing compounds, which is no surprise given that they are often associated with things to avoid.

Smell involves about 400 unique receptors. Each of the hundreds of thousands of scents we can detect is made of a mixture of different odor molecules. Each type of molecule may be detected by an array of receptors, creating a puzzle for the brain to solve each time the nose catches a whiff of something new.

For years, humans have had categories for colors, flavors and sounds, but when it comes to the sense of smell, things are a mess. Now, just as there are three primary colors and five basic tastes, researchers propose that odors can fall into 10 basic groups.

These molecules stimulate specialized nerve cells, called olfactory sensory neurons, high inside the nose. There are a few million of these cells inside your nose. Each makes one of about 500 different types of odor receptor, enabling it to selectively capture a specific set of odor molecules.

What smell do dogs hate the most? ›

For dogs, citrus scents are the enemy. Citrus scents like lemon, lime, oranges, and grapefruit–especially in high concentrations often found in household cleaners or essential oils–can cause irritation to your pup's respiratory tract, so keep any fresh citrus fruits out of your dog's reach. You know–just in case.

Odorants are first detected in the upper region of the nose by the main olfactory epithelium (OE). In this region, millions of olfactory sensory neurons (OSNs) interact with odor molecules through the odorant receptors (ORs), which belong to the superfamily of G protein-coupled receptors.

Now that we know more about them, we'll discuss the scents they hate! The scents on this list are: Peppermint Oil, Capsaicin, Coffee Grounds, White Vinegar, Garlic, Cinnamon, Predator Urine, Irish Springs Soap, Dryer Sheets, and Rosemary.

Humans Can Identify More Than 1 Trillion Smells.

Olfactory qualities

On the basis of the apparent similarities of perceived odour quality or confusions in naming, it was concluded that there were six main odour qualities: fruity, flowery, resinous, spicy, foul, and burned.
